That's quite a generous 'brief' iamto
I'd look for plants that will harmonise in terms of colour, but will contrast in shape and size, and also foliage. Grasses work well with them.
Alternatively, you might want something to clash more - oranges and bright reds for instances. Big, jungly plants with large leaves like bananas, or lanceolate like Phormiums.
What other plants do you have nearby, what space do you have to fill, and what kind of planting style do you like? That's important - you have to like what you put in
